Maintenance
- Cleaning: Wipe the display and body of the clock with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
- Battery Replacement: The CR2016 backup battery should last for several years. If the clock loses time settings during a power outage, replace the battery. To replace, open the battery compartment on the back, remove the old battery, and insert a new CR2016 battery with the positive (+) side facing up.
- Storage: If storing the clock for an extended period, disconnect it from power and remove the backup battery.
Troubleshooting
| Problem | Solution |
|---|---|
| Clock display is off. | Ensure the USB power cable is securely connected to both the clock and a working power source. The clock requires continuous USB power to display time. |
| Time settings are lost after power outage. | The CR2016 backup battery may be depleted. Replace the battery as described in the Maintenance section. |
| Alarm does not sound. | Ensure the alarm is activated (alarm icon visible on display). Verify the alarm time is set correctly. |
| Display is too dim or too bright. | Press the UP (+) button to cycle through manual brightness levels. If using auto-dimming, ensure the light sensor on the side is not obstructed. |
| USB charging ports are not working. | Ensure the alarm clock is powered via its USB cable. The charging ports only function when the clock is receiving power. |
